' 3 plate 44, upon which the hopper 45, is adapted to slide, is almost entirely closed at its forward end by a plate 55. Plate 55, terminates at its lower end short of the lower edges of sides 41, leaving an opening leading to a vertically restrictedpassage 58, bounded on the side by relatively .narrow members 51, which are attached to, and extend forwardly from, the sides 41. The

space 55, is closed at the top by a plate 58, lying parallel to plate 44, and spaced a distance therefrom greater than the thickness of the discs .53,4

but less than their diameter.V

The lower edge of the plate 58, is of arcuate formation, and is concentric to stud 46. 'Secured to and extending across the lower end of plate 44, is an angle 59, of arcuate formation, complementary to the edge of plate 58. Angle 59, closes the forward end of the passage 56, except for an .opening at the center which communicates with arelatively narrow channel shapedtrough 80, just wide enough to permit the passage of single discs 53. The .lower ends of the narrow members I51 and the lower edge of the plate 58 are adapted to bear against the upstanding leg of the angle 59, but are free to slide thereon when the hopper 45 is in motion.`

.Y Thetrough 60, which leads to the nail driving mechanism is preferably fitted with a wire 6|, which extends for its entire length, and prevents the discs 53, from-being displaced during transit.

cured to the frame of the machine by means of brackets 68. Secured to the under side of plate 64, are arcuate flanges 69, which extend downwardly into the space l, and contact the inner sides 41, of the hopper 45, in driving relation.

The frame 53', is reciprocated by means of a disc 10,. eccentrically mounted on the lower end of a shaft 1|, which is driven by the sprocket 29, and chain 35, aforementioned. The shaft 1|, is journalled in a pillow block 12, mounted on a transverseangle 13, secured to the frame 2|, of `,theirnachine; The disc 10, is adapted to fit loosely betweenv the sides 55, of the reciprocatingv frame 63, and rotate in contact therewith. Rotation of the disc 10, therefor, causes the frame 03, to

reciprocate upon the rods 52.

The motion of frame' 93, is transmitted, by means of the flanges 69, to the hopper 45, which is caused to oscillate upon the stud 45.

Nail conveying mechanism Supported Awithin `the framework 2|, of the machine, is an open hopper 14, adapted to be loaded at its lower end with nails 15. The bottom of the hopper 14,A in transverse section, slopes downwardly toward the upper run of an endless 'conveyer belt.1 8, whichis fitter with spaced attachments 11.

lin, longitudinall relationship, with the bottom of The belt 16, runs coincidental,

the hopper 14, which is equipped with a relatively shallow V-shaped extending trough 18, as shown in section on Figure 6. The trough is formed with downwardly extending flanges 19, which serve to guide the belt 16, and also prevent the loss of nails through the space in which the upper run fof the'belt travels.

'I jhe, belt 18, is driven by the aforementioned sheave 4|, and is supported at its lower end by an idler sheave 90, mounted on a shaft 8|, which is journalled in pillow blocks 82. The belt 16. is adapted to travel in a direction that causes its top run to move upwardly, and thus convey nailsfrom the hopper 14, and up the trough 18, which extends to the end of the top run of the belt. Located beneath the sheave 4|, and being adapted to receive the nails as they fall from the belt 15', is a chute 83, which slopes downwardly to, and connects with, the upper end of a trough e4, shown in section in Figure 7.

Rotatably mounted in the trough 84, is a conveyer screw 85, which is driven by a bevel gear 86, adapted to mesh with the aforesaid gear 35, mounted onthe shaft 3|. The trough 84, has a longitudinal slot 31, in the bottom thereof which extends from a point adjacent the upper end of the screw 85, to the lower end 88, of the trough 84, said lower end being located in, and communicating with, the hopper i4. The sweeping action of the flight of the rotating screw causes the .nails to fall through the slot 81, however, theyare prevented from falling all the way through by angles 89, secured to the under side of the trough 84, in offset relation with the edges of the slot 81. The angles 89, support the nails by the under side of the heads, while the body portion is suspended between the adjacent faces of the angles. Angles 89, extend downwardly through the lower end of hopper 14, and connect with the nail driving mechanism.

N ail driving mechanism Bridging the angles 42, near ythe lower ends thereof and secured thereto, is a base plate formedwith a centrally located boss 9| and an upstanding stud 92, upon which is journalleda rotatable head 93. The plate 90 has mounted thereon, adjacent its outer edges, a pair of upstanding brackets 94, to which are attached pillow blocks 95, mounting shaft 96. Fixedly mounted upon shaft 96, is a bevel gear 91, a concentric roller 98 and a pulley 99, adapted to drive the shaft in cooperation with a motor |00 and its pulley |0| and belt |02.

The upper end of the stud 92, is supported by a strap |03, which is secured to one of the brackets 94. A collar |04, is located on the stud 92, on its reduced upper end, and the strap '10.3, is securely .clamped to this collar by means of the nut |05. The collar |04, also forms a shoulder which holds the rotatable head 93, in its place on the stud 92. 1

The rotatable head 93, is provided at its upper end with a bevel gear |06, which meshes with gear 91, and is driven thereby. It is also provided with a pair of annular concentric flanges |01 and |08, which are spaced apart, and are designed with a plurality of drilled bosses, |09 and L| I0, respectively, adapted to receive nail driving plungers Ill, in sliding relation. The Dlungers are maintained in their normal position by means of, compression springs H2, acting against lthe collars H3, which are secured to the plungers by means of pins ||4. Four plungers are illustrated; however, the machine can be equipped with a larger or smaller number of plungers, and still function satisfactorily.

Firmly secured to the rotatable head 93, in the order named and commencing with the upper member, are a nail extractor H5, a nail positioning plate H6, a fiber disc extractor H1, and a roller` thrust bearing H8, adapted to. rotate ...against the face ofthel boss 9|, on thebaseplate ats-moco ".thel "slots I 2 5, 'ar'efaired i'nto `fthe periphery'zof the extractor I t5', .in :order to provide fa; smooth .Team-like surface -The holes |24, which `are.- so 'Ipositionedfas Ato be` in assembled alignment .with "fthe plungers I I Aare suiiciently .large to receive .stthe plungers,fand also yto allow the nails 15, to ipass completely through them; the Aslots |25, f'however, 'Jwhile vfreely admitting the. body yof vthein'ail, are not `sufiiciently wide for the :head yf'to pass through.

The nail `positioning plate, which is also -Ldesign'edto be in'ialignment with the head 93,

v--van'dtheplungers is'provided with theholes S'| |9,`and |20. The nail positioning features com- .prise four'spaced holes |26, suihcently large to `:admit-...the bodyof the nail I5, and counter-drilled for ka portion of their depth to enlarge them sufficiently to receive .the nail head. The bottom =1of..lthe counter--drilled portion vof the hole is fcountersunk, lforminga funnel like opening which fse'rvescto guide Athe point ofthe nail into the '.'smaller-hole holes .126, earel opened radially to the periphery -of--the member v'|||i, 'in-orderthat the nished nails :can fbewith'drawn.

In a machine for producing furring nails, a frame, a rotating head on the frame, a plurality of circumferentially spaced holes in said head, a plunger carried on said head above each hole being reciprocable into and out of the opposite hole, the lower portion of each hole being open toward the head periphery to permit lateral insertion of a disk into the hole, a relatively stationary nail feeding chute leading to the top of the holes in sequence as the head is rotated, the upper portion of each hole being spaced from the periphery of said head, said head having slots extending from the upper portion of each hole to the periphery of the head and being adapted to guide a nail from the nail feeding chute into the adjacent hole, a relatively stationary disk feeding chute leading to the lateral open side of the hole being carried past said disk feeding chute as the head is rotated for inserting a disk in advance of and below the insertion of said nail into each hole, said lower portion comprising disk-seating means to support said disk in registry with said hole under said nail, a relatively stationary plunger actuator above vsaid head following said chutes with respect to the direction of rotation of said head to move the plunger for driving the nail into the aligned disk, and an ejector means following the plunger actuator location with respect to the direction of rotation of said head to remove the assembled furring nail through the open side of the lower portion of the hole as the head is rotated.

9. In a machine for producing furring nails, a rotating head having a plurality of circumferentially spaced holes, a plunger aligned with the top of each hole and moving aligned with respect to the'holes, a relatively stationary feeding device; a relatively stationary plunger actuating device spaced circumferentially from the feeding device in the direction of rotation of said head, a relatively stationary ejector device spaced circumferentially from the plunger actuating devicel in the direction of rotation of said head, the lower portion of each hole being laterally open to the periphery of the head to permit lateral insertion of a disk, said feeding device including a nail chute above the top of the opposite hole, the upper portion of each hole being spaced from the periphery of said head, said head having slots extending from the upper portion of each hole to the periphery of the head and being adapted to guide a nail from the nail i chute into the top of they hole, a disk chute to feed a disk into the laterally open lower portion of the adjacent hole below said nail; said lower vportion comprising disk-seating means to support said disk in registry with said hole under said nail, said plunger actuating device engaging each plunger brought to it by said head for moving said plunger into said hole and driving said nail through said disk and into the laterally open portion of the hole; and said ejector device being in the path of the assembled furring nail for urging the furring nail peripherally outwardly from said lower open portion of the hole.
